Do you know what we were saying, about the world revolving? It's like when you're a kid, the first time they tell you that the world is turning, and you just can't quite believe it, because it looks like that it's just standing still... I can feel it!... The turn of the Earth!... The ground beneath our feet is speeding at a 1000 miles per hour. The entire planet is circling around the Sun at 67000 miles per hour... And I can feel it, we're falling through space, you and me, clinged unto the skin of this tiny little world, and if we let go... That's who I am, now, forget me, Rose Tyler!
